DUMPING-SCOW.

SPECIFICATION forming part of Letters Patent No. 315,918, dated April 14, 1885.

Application filed October 3, 1884.

To all whom, it may concern:

Be it known that I, JOHN DUNN, of Jacksonville, in the county of Duval and State of Florida, have invented a new and Improved Dumping-scow, of which the following is a full, clear, and exact description.

The object of my invention is to facilitate the dumping of a load from a scow, either all together or in separate parts or quantities, as may be desired.

The invention consists of the combination, with ascow,of a tilting deck or decks; and it consists, further, of details of construction and combinations therewith of other parts, substantially as hereinafter more fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal elevation of my improved dumping-scow, parts being in section. Fig. 2 is a cross-sectional elevation of the same. Fig. 3 is a plan view of the same. Fig. 4 is a vertical sectional view of the fiveway cock. Fig. 5 is a sectional plan view of the same on the line :0 :0, Fig. at.

The scow A is provided in its well with a bnlk'head, B, running fore and aft, and provided in its top with a longitudinal groove,0, for receiving a trunnion rod or bar, D, surrounded by eyes E, secured to the under sides of wings, leaves, or platforms F at their inner ends, thus adapting the said leaves to swing up and down. The free ends of the said leaves extend to the sides of the scow. 'Below the leaves platforms G are arranged, which extend from the top of the bulk-head downward and outward to the sides of the well. At the outer end of each swinging leaf or wingF two standards, H, project upward from the bottom of the scow, one at each side of each aving or platform, the said standards project- (No model the top of a cylinder, M, held vertically between the posts of the standard, at the lower ends of the same. Anti-friction rollers Nare held in the upper edge of the cross-head outside of the standard H, and on the said rollers the leaves or wings F rest at their free ends. Between the wings or leaves F upright sheet-metal partitions O are formed on the inclined platform, G, to prevent the load on one leaf or wing, when the same is lowered, from sliding on the platform G under the adjacent raised wing or leaf F. The two cylinders M of each leaf or wing F are connected by a pipe, Q, and the several pipes Q are connected by the pipes 1? P 1 P with a closed cylindrical vessel or cup, R, in which an inverted cylindrical cup, S, is held to turn, the cup S having an aperture, .9, in its side near the top, and four apertures, s, in its side near the bottom. A square-headed round boss, T, projects from the inverted cup S through the top plate of the cup R, and serves to turn the cup S in the cup R. The cup S is connected by a pipe, V, with the pump-cylinder W, also connectedby a pipe, a, with an oil or water tank, I), connected by four pipes, c, with the four pipes P l? P 1 the said pipes being provided with three-way cocks l? at their junc tions with the pipes o.

The scow is operated in the following manner: Before the scow is loaded oil or water is forced into the several cylinders M, to force the several piston-rods L npward,whereby the outer ends of the wings or leaves F are raised and the leaves brought into a horizontal position or flush with the deck of the scow, as shown in Fig. 2. The load is then deposit-ed on the leaves or wings F. When the scow is to be emptied, the wings arelowered together or separately by permitting the oil or water to pass from the cylinders H, through the pipes Q, P, P P and P, and a, into the tank 6. The leaves descend until they rest on the inclined platforms G below them, and then the load on the wings, which are now inclined, slides down the said wings or leaves and drops into the water. The wings or leaves are again raised,when they are ready to receive a fresh load. The scow can be dumped or unloaded 2o shown and described.

without requiring it to betilted or traps in the I 4. In a scow, the combination, with the bottom to be opened.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a dumping-scow, the inner hinged decks or wings, disposed to stand normally flush with the main or fixed deck, said inner decks having their opposite hinged edges sup ported about centrally of the boat, and their outer free edges arranged to have movement within a well in the boat below the plane of the main deck, substantially as and for the purpose set forth.

2. In a scow, the combination, with the bulkhead B, of the trunnion-bar D on the top of the same, the inclined platforms G, the wings or leaves F, hinged on the said bar, and of devices for raising and supporting thewings at their free ends, substantially as herein 3. In a scow, the combination, with the hinged wings or leaves F, of the standards H, passing through slots in the leaves or wings, the cylinders M, and the piston-rods L, supporting the outer free ends of said leaves or wings, substantially as herein shown and described.

hinged wings or leaves F, of the standards H, 0 passing through slots in said leaves or wings, the cylinders M, and the piston-rods L, having the cross-heads K, provided with the rollers N, supporting the outer free ends of the said leaves or wings, substantially as herein shown 3 5 and described.

5. In a scow, the combination, with hinged wings or leaves, of cylinders arranged below the free ends of the wings, and containing piston-rods moving in guides and sup- 4o porting the outer free ends of said wings or leaves, and a pump for pumping oil or water into the cylinders, substantially as herein shown and described.

6. In a scow, the combination, with hinged wings or leaves, of cylinders below the free ends of the wings,and containing pistons supporting the outer free ends of said wings or leaves, and of a multiple-way cock connected with a pump and with the cylinders below the several wings by pipes, substantially as herein shown and described.
